Country singer drinks a little drink, gets a little wild at free outdoor show in Nashville.

At one point, Eric told the 4,000-ish fans: “A few weeks ago, we had the No. 1 record in the world two weeks running. So Kanye and Jay Z can kiss my a#@!”

Eric's label, Capitol Records, held the show right on the street outside a popular strip of bars in Nashville, within a hundred yards of Music Row. Alan Jackson was the headliner, but Eric was the rowdiest.

He told the crowd that he used to get drunk in those bars and now he’s getting drunk onstage.

Then, four or five songs later, Eric opened two beer cans and poured them in his mouth, on his head onto his shirt.
